The victim was arguing with another man when he was shot repeatedly on E. 108th St. near Flatlands Ave. about 8:40 a.m. He died at the scene.

A man was shot to death as he sat inside an SUV in Brooklyn Saturday morning, cops said.

Esley Porteous, 33, was sitting in the front passenger seat of the gray Ford Explorer on E. 108th St. near Flatlands Ave. in Canarsie when the gunman approached and opened fire about 8:40 a.m.

Porteous was shot in the chest and died at the scene, cops said.

The shooter, who was wearing all black, ran off and was still on the loose Saturday evening, cops said.

The SUV was parked next to a fenced-off section of E. 108th St. that was under construction outside the Breukelen Houses. Investigators covered the SUV with a sheet as grieving friends and relatives gathered and shed tears.

Cops were scouring the street for surveillance cameras that may have recorded the crime or the triggerman’s escape.

The shooting was the first homicide in Canarsie this year, officials said. Seven murders were investigated in the neighborhood last year.

Saturday’s killing comes as the NYPD marks a 17% decrease citywide in homicides so far this year.

As of Wednesday, 15 homicides had been reported in the five boroughs — compared to 18 during the same period last year.
